"Hold up that coin so we can see a little better." Jakobee whispers in Rosalia's ear as his hand erupts in flames. Ready, just in case it is not an object but a corrupted creature.
As Rosalia and Jakobee ponder whether to continue on up or not, Rosalia notes that the opening is definitely wide enough for two or three people (on intimate terms with each other) to squeeze through together. Jakobee notes the same thing, but his mind quickly diverts to figuring out how he can make that happen with Rosalia.
OOC: Both Rosalia and Jakobee can roll spot rolls. I'd like to point out that the other characters can potentially make the climb safely with fairly mild climb checks. The natural sediment cement of the slope is coarse and gives decent traction, but by the same token is rough on flesh sliding on it. I'm just sayin'.
I made a quick and dirty sketch of the situation. Hopefully it makes things clearer for players.
John is tired of waiting. He climbs up the rope to join the cozy two.<take ten?> "alright jakobee, J-lo Rosalia. what are you two gawlking and whispering at. Hmm?"
